[0 (MZ whom, ir; may concern,.-

Beit known that I, JAMES l). CLARK, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Vfired Plating and Dipping Racks; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to numerals of reference marked thereon, which form a part of this specification.

The objects ol' this invention are to provide a dipping rack or holder which will be more durable and less liable to reduce the electrolytic fluid because of undue deposition of metal on the rack and to secure other advantages and. results, some of which may be hereinafter referred to in connection with the description of the working parts.

The invention consists in the .improved dipping-rack for electroplating articles and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth, and finally embraced in the clauses of the claim.

Referrin to the accompanying drawings, in which li e numerals of reference indicate corresponding parts in each of the several iigures, Figure l is a front elevation of the improved rack. Fig. 2 is a side View of the same, partly in vertical section. Fig. 3 is a sectional view taken at line Fig. i is a detail view oi a portion oi a certain center piece or bar; and Fig. 5 is a section thereof, taken at line y.

In said drawings, 6 indicates .a center piece or bar to which a series of transverse bars 7 7 are rigidly secured, the said bars being preferably oi wood or other non-conductive material and of suiiicient strength to sustain a number of articles to be plated. To each of .the said transverse bars are attached a series of metallic hooks 8 8 8, from which the articles to be plated are suspended, said hooks being preferably of wireA and Abeing electrir cally conductive and each of' a series connected to a common transverse wire 9, extending lengthwise 'of the said transverse pieces or bars 7. Said Wires 9 are in turn each in electric connection with a vertical wire l0, which is preferably hooked at its. upper end, as at 1l, and serves as a suspensory supporting connection for the rack. The wooden upright or center bar 6 is preferably grooved longitudinally at about the longitudinal center of its front face as at l2, in Figs. 3 and 5. The said groove serves as a receptacle for the conducting and supporting wire 10.

To prevent the Wires 9 and 10 from being coated With an electrodeposit of metal from the electrolytic bath, the said wires are cov-- ered and protected from such iiuid by plates 13, of wood, which cover the grooves, and in like manner the wires 9 in grooves 7l, Fig. 3, of the transverse pieces, preferably at the sides opposite that from which the hooks project, are protected by horizontal coveringpieces 14C, attached to the horizontal bars 7.

In the preferred construction the hooks 8 are doubly hooked or hooked at opposite ends, at their upper ends being bent to extend around the wires 9, lying in the longitudinal grooves of the strip 7 ,-and thus said hooks are not only brought into close contact with said wires 9, but the said. hooks are held in place with greater security and firmness, as will be obvious. From said. conducting and supporting wires 9 the hooks project through perforations in the bar 7 and thence downward to receive articles to be plated. I prefer to arrange the hooks of one series so that they project oppositely from the hooks of the series next above and below, as indicated in Fig. 2. By this arrangement Iam ,enabled to suspend a larger number of articles from the rack without interference, as will be obvious, which conduces to economy and quick results. oppositely disposed, I prefer to double the suspensory-wire 10, as shown in Fig. 2, where the said wire extends longitudinally downward at one side oiE the central bar and then passes through. 'a hole in said bar and thence extends upward at the opposite side of the said bar, 'the said extensions .being all protected bylapplied pieces of non-conductive matter.

Having thus described the invention, what I claim as new is 1. The improved plating-rack, comprising a center bar, a series of transverse bars secured to said center bar and a series of hooks supported by one of said transverse bars, and protected conducting-wires in electrical connection with said hooks and with a suspensory conducting-wire.

2; The combination with the longitudinally-grooved center bar and lonfitudinallygrooved horizontal bars attached thereto of When said hooks are thus Y IOC conducting-Wires arranged in the grooves of said bars and hooked Wires in connection With the Wires of the horizontal bars, substantially as set forth.

3. The improved rack, comprising a series of horizontal bars having longitudinal con.

ducting-Wires protected by insulation and thus prevented from coming into contact with the electrolytic fluid, of Wire supports for the article to be plated, hooked onto said conducting-Wires and in electrical contact therewith.

4. The improved plating-rack having a horizontal bar With a protected conducting- 'Wire arranged longitudinally thereon, and a electrical contact with said conducting-Wire,

substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 16th day of June,1905.
